Hammer beam is a term used to describe a horizontal structural element in the roof of a building that is usually supported by brackets or hammer posts. The term is often associated with the Gothic architecture style that emerged in Europe in the 12th century. Synonyms for the word hammer beam include brace, truss, rafter, strut, and beam. These terms all describe different structural elements that perform similar functions in supporting and distributing the weight of the roof. While the term hammer beam is specific to a particular architectural style, the use of these other terms is more general and can be applied to a range of construction types and designs.
